BURNER STRUCTURE

摘要

To provide a burner structure in which a burner is capable of highly precisely controlling the flow rate of the air for combustion within itself. An air flow passage (11) in a wind box (12) for injecting the air for combustion into a furnace (1) has a bent portion (13) just before joining with the furnace, and one or a plurality of guide vanes (14) are provided in the air flow passage (11) in the bent portion (13), and also in the bent portion (13), a drift control damper (16) is provided for varying the ratio of flow passage resistances of each of the air flow passages (11) divided by the guide vanes (14).
